I strongly suggest to consider EndeavourOS installer,
which is far more user friendly than anything archibold will ever be.

Finally, the original achievement of archibold has been improved all over.

It is now possible to simply type the following:

# install from scratch Arch Linux
bash

After you've booted Arch Linux through its image,
the command will start installing Arch Linux from the scratch in such machine or,
in case you are already running Arch Linux, into an SD card or USB one.

Remember, a fresh install will format and erase the target disk: choose the right one.

As very first step, we need a bootable version of ArchLinux iso through USB stick or DVD.
We can learn how to burn it in the dedicated page.
Following the Linux/Mac summary where /dev/sdX is the USB path.

Please note it might take 5 minutes or more to complete above operation, be patient.

Once dd has finished, we can use the USB stick from any USB port of the target machine.
Some target might require some extra step and it depends on the bios.
Usually keeping pressed Esc, F2, F10, or F12
during boot should help reaching the boot menu.

The boot option we are interested about is the UEFI ArchLinux one.
If everything goes OK, we should bootstrap into a terminal/console.

As extra requirement the target machine will need to be connected to the Internet.
The preferred connection type is via network cable, but we could use WiFi too.
However, WiFi initial configuration is a bit more advanced, I can give a hint thought:

If after an update your system doesn't boot anymore, try switching to systemd-boot instead, like latest archibold does too.
Simply start your PC through an ArchLinux ISO and type the following to fix your boot.
